Dating

Usain Bolt and his GF are still going strong ... the two hit up Cabo this week -- and the bikini she was rockin' and the mojitos they were drinkin' say they're doing just fine.

Of course ... Bolt and Kasi Bennett have had a very unique relationship over the years -- 'memba the EPIC hall pass she allegedly gave him during the 2016 Rio Olympics??

But, doesn't seem all that other tail has put a strain on their relationship ... 'cause the two soaked in the Mexico rays just fine on Thursday.

There was rum ... white sand ... and Bennett even flaunted all her assets in a tiny bikini for the ex-track star.

Yeah, Bolt likey.

It all begs the question ... could Usain finally be ready to trade in Olympic rings for wedding ones???

Cristiano Ronaldo claims the former U.K. "Celebrity Big Brother" star who publicly accused him of emotionally abusing and threatening her is lying ... insisting he's never even met the woman.

As we previously reported, fashion model Jasmine Lennard went off on social media this week -- claiming she had secretly dated Ronaldo for a decade and was subjected to all sorts of disgusting behavior, including death threats.

Lennard even posted audio clips she claimed captured Ronaldo making offensive comments -- but there's one huge problem, Ronaldo claims the voice on the tapes is NOT him.

"Mr. Ronaldo has no specific recollection of meeting Ms. Lennard 10 years ago or at any point," his legal team tells TMZ Sports.

"He has not had a relationship with her and he has not had any contact with her, whether in the last 18 months as Ms Lennard suggests, or otherwise."

"The voice notes posted by Ms Lennard on social media are not of Mr. Ronaldo. Mr. Ronaldo will take appropriate legal action in due course."

Jeff Bezos was having a relationship with former "So You Think You Can Dance" host Lauren Sanchez, and according to the National Enquirer, that's what ended his marriage.

Sources closely connected with Lauren and her estranged husband, William Morris Endeavor mega-agent Patrick Whitesell, tell TMZ Lauren was indeed "seeing" Bezos in the later part of 2018. The sources add Sanchez and Whitesell separated last summer and are in the process of divorcing, and her relationship with Bezos did not begin until after her separation.

Same goes for Bezos. We're told he and MacKenzie were also separated when he and Lauren started hooking up.

We're told both Patrick and MacKenzie have known about the relationship for months.

Our sources add, Jeff and MacKenzie have known Lauren and Patrick as good friends for 10 years. Lauren and Patrick have a home in the Seattle area -- where Jeff and MacKenzie live -- and they spend a lot of time there, especially in the summer.

Lauren is an accomplished pilot of helicopters and planes, and a lot of time in the air up there. She owns a helicopter and production company.

And sources tell us, the relationship between Sanchez, who also hosted "Extra," is not "fleeting." It is still going on strong.

Ryan Garcia is one of the fastest rising stars in boxing ... with a 17-0 record and a huge contract with Oscar De La Hoya's Golden Boy Promotions.

But, what he REALLY wants ... is a date with Selena Gomez!!

"She's single so lemme shoot my shot," the 20-year-old told us ... "Lemme take you out!"

Garcia even gave a pitch to Gomez ... saying, "I would protect you, you know!?"

He's right ... dude's got a lethal left hook and has been obliterating opponents since he turned pro at 17 years old back in 2016.

Since then, Garcia has developed a huge following -- with 1.7 million followers on Instagram! He's also starring in a new series "On the Ropes" produced by the Brat digital studio. Dude's killing it right now.

Garcia tells TMZ Sports he's working on closing a deal for his next fight in March -- but he's also seriously interested in fighting Tenshin Nasukawa ... the guy who got beat up by Floyd Mayweather.

"He should fight me," Garcia says ... while making his case for why the two 20-year-olds would actually be an entertaining matchup.

Long story short ... they're more equally matched in size and experience -- but Garcia says the outcome will be the same ... Tenshin gets KO'd.

Trevor Lawrence's girlfriend landed a winner ... and she knew it 2 YEARS AGO ... 'cause she predicted her man would win the national championship back in 2017!!!!

The freshman Clemson star has been dating college soccer player Marissa Mowry since early 2016 ... and while we were doing some research on the dreamy QB's lady, we came across this prophecy from January 9, 2017:

"Two more years then you'll be a National Champ😉 #GoTigers"

Not only was Marissa right ... but the fact that Trevor beat out Kelly Bryant to take over the starting gig as a true freshman and lead the Tigers over Bama in the title game makes this just. plain. FREAKY.

The prediction was bold ... but the confidence in her man was justified -- Trevor was considered one of the greatest high school QB prospects ever.

We've reached out to Marissa for comment (and some lottery numbers) ... so far, no word back.

As if the new 'Bachelor' didn't already know he was a virgin, his suitors (and the show at large) constantly reminded him during the season premiere ... and it got old fast.

Colton Underwood's journey got started Monday night, and as he was meeting the lovely ladies who'll be vying for his heart ...and apparently his crotch. His virginity was on the minds in the mouths of almost every girl. It was awkwardly charming at first, but quickly became a tired gag.

Even worse ... the virgin gimmicks quickly escalated from a chat to full-blown costumes just to land the joke. One girl popped a "cherry" balloon in front of Colton, another teased him with a real peach, and yet another took away his "V" card in a corny magic trick.

But, Alex D. of Boston took the cake (and the award for worst contestant thus far) by creeping out of the limo in a human-size sloth suit and lurching over to him in slow-mo ... staying committed to the whole sloth thing the entire way through.

It was cringeworthy to say the least. Fact is ... Colton's more than just his virginity -- here's hoping the producers of the show realized that before it's too late.

Diddy might want to ask for a refund from his former trainer ... because sources claim the guy he hired to keep Cassie in shape was banging her on his dime ... but she says his timeline is wrong.

Here's what we're told. Diddy's trainer, Jamal Liggin, got so busy he hired several trainers as backup, including Alex Fine. Diddy tagged Alex to train Cassie over the last year.

As we reported, Diddy and Cassie broke up several months ago after a decade-long relationship, but our sources claim Cassie and Alex hooked up before the split. We're told what especially galls Diddy ... he paid Alex to train his then-girlfriend and feels betrayed.

Cassie sure seems smitten with Alex. She has not ever publicly talked about a timeline, but we're told Diddy is convinced there's an overlap.

Sources connected to Alex and Cassie insist the two did NOT start dating until after she broke up with Diddy.

Diddy has bigger issues to deal with, like raising his 3 children after the death of Kim Porter in November. Diddy was destroyed when Kim died, saying they were more than soulmates.

Ariana Grande is about that single life heading into the new year, and probably for the rest of her days ... according to her, anyway.

Ari responded to an article on Tuesday which speculated on who she's been seeing lately by hilariously tweeting, "can they tell me too?" She followed up with, "spoiler for the rest of this year / probably my life: it's no one. please refer back to this tweet for future questions."

It goes without saying ... AG's had it rough this year in the love department. She called off her engagement with 'SNL' star Pete Davidson ... and, of course, her ex, Mac Miller, tragically died of an accidental overdose from a mix of fentanyl and cocaine.

Ariana seems to be joking about the never dating again thing, but her point is coming through loud and clear ... her dating life shouldn't be the subject of such scrutiny in 2019.

Have you heard her new single yet? It's her ... she's single.

Trey Songz put rumors that he's been dating Steve Harvey's 21-year-old stepdaughter to rest on Monday ... by confirming they're absolutely boo'd up heading into 2019.

The R&B singer was performing at the Regency Ballroom in San Francisco for New Year's Eve and people couldn't help but notice a girl was clinging to his back with her arms wrapped around his torso as he sang. Well, that was Lori Harvey ... Steve's youngest stepchild.

She showed up on his Insta story earlier in the night wearing the same gold dress that was seen on the chick wrapping him up. No question ... it was her, and they're into each other.

Trey and Lori have been hanging out a lot through the holidays, and it now seems they're an item in the new year.

Lori's an up-and-coming model who's walked for Fashion Week in Milan and Paris. It's clear why she's caught his eye ... she's gorgeous.

Olivia Culpo and Danny Amendola may have forgotten old acquaintances -- at least one of them -- because it looks like they're back together.

Danny and Olivia each posted identical videos of fireworks to their IG stories ... videos obviously shot on New Year's Eve.

The videos were shot at a beach location, and the fact he plays for the Dolphins may be a geographical clue.

Olivia and Danny broke up a few months ago after he hit the beach with a super hot woman. After the pic surfaced, Olivia proclaimed she was keeping the $12,000 Rolex she bought for Danny's birthday.

If this is real, it will be the third time Danny and Olivia got together. They met in 2016, dated for 2 years, broke up, got back together last year but the woman in the bikini buzz killed that one. But, old flame don't douse easily.

Diddy might be missing his ex, Cassie, but she sure as hell ain't missing him ... not by the looks of this photo of her kissing another dude, anyway.

This one's tough to swallow if you're a Diddy/Cassie stan and had any hopes of them getting back together. Diddy posted an intimate shot of Cassie on his IG story Friday night ... and the same shot again early Saturday.

The message we're reading from this ... he's still got feelings.

Unfortunately for him, Cassie appears to have moved on with a younger man ... who she revealed on her own Insta account just hours after Diddy put up his tribute. Unclear if this was in direct response to that, but Cassie seems to be sending a message of her own.

The dude in question has reportedly been identified as fitness and health guru Alex Fine. As if the name isn't enough ... he's also a natural born stud. And, now ... Cassie's into him.

Interestingly enough, Cassie was seen with Diddy shortly after Kim Porter died last month ... which sparked rumors they might be rekindling their 10-year relationship following their October split.

Looks like that reunion was just moral support though, 'cause Cassie hasn't been spotted with Diddy since.

Pete Davidson is ending the year on a good note -- he's got a new haircut ... and, possibly, a new girl by his side.

The 'SNL' star was hanging out in Miami Saturday with a mystery girl at the Mandarin Oriental hotel, where eyewitnesses tell us they were chatting over lunch. Hard to tell who this chick is, but one thing's for sure ... Pete seems to be happy in her company.

It's been a rough year for Pete, so it's great to see he's enjoying himself to round out 2018 ... and going wherever the hell his heart desires.

You'll recall ... he was just in Cleveland last weekend watching Machine Gun Kelly's concert, and had the best seat in the house. He was covered up then, so we couldn't make out his new 'do. Now that we're seeing it in all its glory, we gotta say ... he looks fresh.

As for whether this was another date for Pete -- he recently went out to dinner with a previous mystery girl -- or just chillin' with a friend ... we simply don't know.

Corinne Olympios spent Xmas day enjoying the Miami Beach sun with her boyfriend.

The former "Bachelor" and "Bachelor in Paradise" contestant was hanging with Jon Yunger. She's been seeing him since May.

This pool encounter turned out a lot better than a previous outing last year, when Corinne accused DeMario Jackson of sexually assaulting her on the set of "Bachelor in Paradise." She claimed she was super drunk and did not give consent to the sexual contact. The allegation brought filming of "BIP" to a halt.

An investigation -- which included video of the encounter -- concluded Corrine was a willing participant and there was no sexual assault. Filming resumed, but Corrine and DeMario were no longer on the show.

Nicki Minaj's new boyfriend wasn't just convicted of attempted rape -- he also went to prison for killing a guy ... and now we know the story behind his manslaughter conviction.

Law enforcement sources tell TMZ ... Nicki's new man, Kenneth Petty, rolled up on Lamont Robinson one early morning in April 2002 and opened fire on him on a street corner in Queens, NY.

We're told Petty drove to the crime scene with a group of cohorts, hopped out of the car, walked across the street where Robinson was hanging out, pulled out a gun ... and shot him in the stomach 3 times. Our sources say he then fled in the vehicle with the group.

We're told police who investigated the crime at the time did not believe robbery was a motive -- they suspected it to be a targeted hit over a gang beef. One investigator who was on the OG case told us he could only recall the shooting was over some "bulls***."

According to court docs, obtained by TMZ, Lamont -- who only survived for a short time -- ID'd Kenneth in a photo lineup when police went to question him in the hospital. The docs say he nodded his head to confirm Kenneth had shot him, as he couldn't speak. He died soon afterward.

Kenneth was initially charged with 2nd-degree murder, but pled guilty to a lesser charge of 1st-degree manslaughter. He served 7 years in prison, and got released in 2013.

As we reported ... Nicki's beau also did nearly 4 years behind bars after being convicted of attempted rape as a 16-year-old about a decade prior.

Like we've told you, Nicki isn't fazed by Kenneth's checkered past ... as we're told, she and Kenneth have already discussed having babies and getting hitched.

Cardi B was all over Offset Friday ... hugging him and you might even say hanging on for dear life.

Cardi and Offset were vacationing in Puerto Rico, and it's a real sign his full-court campaign to win her back has worked.

Eyewitnesses tell TMZ they seemed very much like a couple as they laughed and played on and in the deep blue sea.

They were there with friends. No sign of baby Kulture, but it's a safe bet she's there.

Cardi has a set Friday night in San Juan at the Electric Holiday festival.

We don't know for sure if Cardi has taken Offset back, but there have been signs for more than a week that the ice is thawing.

Cardi announced her split with Offset on December 4. As we reported, he crashed her stage at the Rolling Loud Music Festival in L.A. last weekend, and she was clearly not receptive but it looks like things may have changed.

Nicki Minaj's new beau is the ultimate bad boy -- and has been for quite some time, including while he was behind bars.

Kenneth Petty's inmate disciplinary history, obtained by TMZ, shows Nicki's BF was written up 18 times from 2006 to 2013 while he was serving time for a manslaughter conviction in New York.

Some of Petty's violations were major -- he got slapped with 2 violent conduct violations in 2010 for threats and fighting. Before that, he also racked up another fighting violation, and 5 violations for disobeying a direct order.

He got off to a ROUGH start too ... just one day after he entered the prison he got tagged for creating a disturbance.

There was also a 2009 incident where he was cited for 9 separate violations, and got 4 months in solitary as punishment. Mostly though ... he lost phone, recreation and commissary privileges for bad behavior.

As you know, Minaj's BF was convicted of first-degree attempted rape in 1995 when he was 16. He served almost 4 years for that ... before the 2006 manslaughter conviction.

Still, the man did his time ... and our Nicki sources say she believes Kenny -- an old flame from Queens -- has changed, and she's happier than she's been in years.
